  summary: "Divides a variable reference by sparse updates."
  description: <<END
This operation computes

```python
    # Scalar indices
    ref[indices, ...] /= updates[...]

    # Vector indices (for each i)
    ref[indices[i], ...] /= updates[i, ...]

    # High rank indices (for each i, ..., j)
    ref[indices[i, ..., j], ...] /= updates[i, ..., j, ...]
```

This operation outputs `ref` after the update is done.
This makes it easier to chain operations that need to use the reset value.

Duplicate entries are handled correctly: if multiple `indices` reference
the same location, their contributions divide.

Requires `updates.shape = indices.shape + ref.shape[1:]` or `updates.shape = []`.
